Coolant Flush
Hello, can someone direct me to a DIY thread for this or direct me to an existing thread? I'm sure one exists already. Can't figure out where to drain it...no petcock (old school) or drain plug or radiator main cap that I can see. 2016 X3 35i
I already bought OE BMW coolant. Thanks. |

seems like they want us to drain by removing the hose and spilling it

not sure if you've already replaced your expansion tank .... but here, just in case:

ONE MORE THING. The hose at the bottom of the expansion tank is beyond brittle. I think I broke mine simply by sneezing on it. I bought 1 to have on deck, just in case ... and I did end up needed it / using it

I'm getting ready to drain/re-fill my cooling system. Car has N52 (normally aspirated) engine. I'm wondering about this 'pull the hoses off the radiator' business??? Both the main hoses look like they connect quite a distance above the bottom of the radiator, so I'm wondering if that is best place to drain?
I got under the car, see pic - there is one smaller hose that connects to raditor very near the radiator's bottom/lowest point. I'm thinking this would be THE hose to remove. Thoughts/comments/recommendations, etc.. ? Thanks/Bill |

Have you replaced your Oil Filter housing gasket?? If not at 92k miles it's def. Due... And only going to get worse... At this point you need to drain and refill with water and degreaser( 4-8oz ) run the bleed procedure and drain... Repeat till the water comes out clean... With a final rinse of only water... Then drain and refill with coolant... Only after you've replaced the OFHG.. Ask me how I know all that.... Yeah it was a mess when the OFHG finally blew out completely and the low oil pressure warning scared the shyt out of me... Turns out oil pressure is higher than coolant pressure this why the oil enters the coolant and not the other way around... |

Mine made it to 181k and was still going when I replaced it while the engine cradle was off the car, so it made it easy access from the bottom... No way I wasn't going to take advantage of that time to replace...
Same thing about the starter when I replaced the HPFP... You want a great reliable BMW.... It's a labor of love and a shyt ton of maintenance... Wait for it to break and it will break you. |
